Supps for Damn Rotator Cuff!

I've been suffering from a rotator cuff injury for about the last two months, and it hasnt really gotten much better. I dont know much about what, if anything, I can do to help it recover quicker. Im really eager to get back in the gym though. A friend recommended Glucosamine Chondroitin (Optimum Nutrition's Glucosamine + CSA @ 1fast400.com). I read up on the product and it says it is for joint relief. I guess my question is if anyone has had any experience with this product or knows if it might be a good choice to help me get over my injury? Also, if anybody knows of anything else that might help me out, it would be greatly appreciated. Thanx in advace for your replies.

I used to have constant shoulder pains that acted up real bad when i would bench and do certain other exercises. I then went on a cycle of 1t-pro and made sure to rub it on my shoulder often. Within a week my shoulder pain was gone. This was most likely due to the dmso. So i would agree with JWeave and say try rubbing some dmso or msm on it. One is a derivative of the other i forget which way it goes though.
